Sea urchins are marine animals that crystallize calcite as the major skeleton building material. Regular sea urchins consist of a spherically shaped, calcitc exoskeleton onto that the spines are attached in a radial arrangement. We investigated the Ultrastructure of teh eSpines by means of EBSD and TEM.
